2.3 Connecting to the water supply

•
In the building's water system install a
separate stop tap with filter for each
unit (0.5 mm). This should only be
opened when the combi steamer is in
operation.
•
The water pressure (flow pressure)
must be at least 200 kPa (2bar) and
max. 600 kPa (6 bar).
•
Connect the water via a pressure hose
with a ¾" screw connection.
Before connecting the water
installation, rinse out the on-site water
pipe.
•
Find out about the water quality and
water hardness from your local water
company.
•
The water must have the following
properties:

N.B:
7°dH equates to
•
Connect a sediment filter (0.08 mm) in
series if the water is impure.
•
With a chlorine concentration
(Cl > 0.1 mg/l) connect an activated
2
carbon filter in series.
•
For a water hardness >7° dH the
manufacturer recommends a hydrogen
ion exchanger (partial
demineralization).
•
When exceeding the chloride value
-
(Cl ) the manufacturer recommends full
demineralization. The resultant water
quality must match the details above
(cf. table).
•
If you install a combination of filters
and water treatment units, take care
with the order in which they are
installed: sediment filter, activated
carbon filter, hydrogen ion exchanger,
stop-cock.
